"less bloat and more speed at the expense of a built in rss reader."
Opera displays feeds just fine, and offers links to subscribe to them via various web services. No, I don't use my browser "as a feed reader" either, but it surely isn't asking much for a browser to be able to display a feed.
"More speed" by using plugins? First off, Opera again: More features, less size, more speed, super fast installer that actually respects you. So no, not having a feed reader doesn't mean the program is faster. Programming skillfully does. And hey, now Opera even has Extensions *on top* of all that slickness. THIS is how you do it, not provide an API so others can do the work for you. (just check our Opera's Dragonfly and then realize how many Firefox plugins that one piece of genius saves you, haha!)
Second, if you implement the functionality via a plugin instead of natively, how is that faster? Oh right, you're comparing a hypothetical browser with a native feature with a hypothetical browser without that feature AND without an installed extension for it... and then you call others misinformed. Huh ^^
